Hi all The casper_library.mdl file seems to be misaligned relative to the scripts. The scripts are trying to set mask parameters that don't exist and are failing. I may be wrong but the casper git repository seems to be broken at the moment.
Use the following to get a version that should work better until it gets fixed at Berkeley; git clone git://casper.berkeley.edu/mlib_devel/kat.git Regards Andrew On 1 September 2010 16:39, melvyn wright <[email protected]> wrote: > Hi Andrea, Dave, Dan, Mark,... > > > This is a nicely detailed description of an FFT implementation problem and > possible solutions.
